Audi announced the first generation A3 (''Typ'' 8L) in June 1995. The model was launched for the European market in September 1996 and marked Audi's return to small cars after 19 years, following the demise of the [[Audi 50]] in 1978. 

The A3 was the first [[Volkswagen Group]] model to use the PQ34 (or "A4") [[Automobile platform|platform]], bearing close resemblance to the [[Volkswagen Golf Mk4]], which arrived a year later. Within three years of the A3's launch, the PQ34 platform was utilised by seven different vehicles.

Initially, the A3 was only available as a three-door hatchback; this was done to give the model a sportier image and differentiate it from the Golf. Offered with [[transverse engine|transversely mounted]] [[inline-four engine|inline four-cylinder]] engines in both [[front-wheel drive|front]] and [[Quattro (four-wheel-drive system)|quattro four-wheel drive]], the A3 was Audi's eighth model to have five valves per cylinder. The dashboard was also used by the first generation [[SEAT León]] and second generation [[SEAT Toledo]].

The United Kingdom received the Audi A3 in November 1996. 

In 1999, Audi expanded the A3 range with the introduction of a five-door hatch and two new engine options; a 1.8 L [[Turbocharger|turbocharged]] inline four-cylinder rated at {{convert|180|PS|kW hp|0|abbr=on}}, and a 1.9 L [[Turbocharged Direct Injection|TDI]] [[diesel engine|diesel]] with [[unit injector]] "Pumpe Düse" (PD) technology and a [[variable geometry turbocharger]]. The four-wheel drive A3 1.8T Quattro used either the {{convert|150|PS|kW hp|0|abbr=on}} or {{convert|180|PS|kW hp|0|abbr=on}} engine, and the same [[Haldex Traction]]-based quattro system as the [[Audi S3]] and [[Audi TT]].

In late 2000, the A3 range was updated with new headlights and taillights, an improved interior, and other minor cosmetic changes alongside the introduction of a six-speed [[manual transmission|manual]] gearbox on the {{convert|180|PS|kW hp|0|abbr=on}} 1.8T and new {{convert|130|PS|kW hp|0|abbr=on}} 1.9 TDI.

With this update, Audi's [[electronic stability control]], traction-control, and brake force distribution systems became standard in some countries.

Although the first generation Audi A3 was replaced in Europe in 2003, it continued to be sold in select markets; Brazilian production of ''Typ'' 8L A3 continued until 2006.

The first generation A3 received a Euro NCAP rating of 4 out of 5 stars.<ref name=EuroNCAPtest1/> Their evaluation concluded "the column lock, adjuster lever and bracket presented hazards in the knee impact area for the driver. These could cause high loads on his upper legs and damage to his knees." The A3 also provided minimal protection for pedestrians, and received two stars out of a possible four.<ref name=EuroNCAPtest1/>

===S3 (1999–2003)===
Audi released the A3-derived S3 in 1999. Only available as a three-door hatchback, the S3 was powered by a turbocharged 1.8 L 20v inline four-cylinder. Early models (1999–2001) produced {{convert|210|PS|kW hp|0|abbr=on}}, with later models (2001–2003) receiving [[variable valve timing]] which increased output to {{convert|225|PS|kW hp|0|abbr=on}}. The engine had a maximum torque output of {{convert|280|Nm|ftlbf|abbr=on}}. The S3 was the first [[Audi S and RS models#S models|Audi S-series]] car to utilise a smaller four-cylinder engine.

The S3's quattro system utilises a Haldex Traction coupling to adjust the bias of torque distribution from the front to rear axle as grip requirements change.<ref>{{Cite web |date=2009-07-31 |title=Audi S3 - CarAutoPortal.com |url=http://www.carautoportal.com/audi/audi-s3.php |access-date=2024-06-22 |archive-url=https://web.archive.org/web/20090731142939/http://www.carautoportal.com/audi/audi-s3.php |archive-date=31 July 2009 }}</ref> Due to this, the S3 typically operates in front-wheel-drive in most conditions.

The S3 was sold in Europe, Japan, Mexico, South Africa, Australia, and New Zealand.

In 2002, the S3 received a facelift, receiving revised front wings, rear lights clusters, single-piece headlight and indicator units, and minor interior trim updates.

Standard features include [[xenon HID headlamp]]s with high pressure washers and auto levelers, front fog lamps, 17-inch "Avus" alloy wheels with 225/45R17 tyres,<ref>[https://www.tyrepressure.org/audi/a3-tyre-pressure/ "Audi A3 Tyre Information"] (28 October 2020). Tyrepressure.org. Retrieved 15 November 2022.</ref> electrically adjustable [[Recaro]] leather seats, climate control, an alarm and electronic stability control with [[traction control system|traction control]].

Options include a [[Bose Corporation|Bose]] sound system, boot/trunk or in-dash mounted 6-disc CD changer, metallic paint, 18-inch 9-spoke RSTT wheels, glass sunroof, centre arm rest, privacy glass (B-pillar backwards), auto-dimming rear-view mirror, parking assist, luggage net, heated front seats, cruise control, aluminium door mirror casings and part leather/Alcantara (blue/silver/yellow) combination seat coverings. Some of these items are standard in certain export markets.<gallery widths="160" heights="160">

===Initial release===
At the [[Geneva Motor Show#2003|2003 Geneva Motor Show]], Audi launched the second generation of the A3, the ''Typ'' 8P, designed by Gary Telaak during 2000 (however, the final design was frozen in 2001). Originally launched only as a three-door hatchback with four-cylinder engines, it featured a new automobile platform (the [[Volkswagen A platform#PQ35|PQ35]] platform), a redesigned and more spacious interior, new petrol engines with [[gasoline direct injection|Fuel Stratified Injection]] (FSI), and standard six-speed manual gearboxes (except on the base 1.6 petrol and 1.9 diesel).

In mid-2003 the line was updated with two sports-oriented models, a 2.0 Turbo-FSI version rated {{convert|200|PS|kW hp|0|abbr=on}}, and a 3.2&nbsp;L [[VR6 engine]] (for the first time) with {{convert|250|PS|kW hp|0|abbr=on}}. Haldex Traction-based quattro on-demand four-wheel drive, and the [[Direct-Shift Gearbox|S-Tronic]] semi-auto gearbox were introduced as options (quattro is standard on the VR6) on models with engines over {{convert|140|PS|kW hp|0|abbr=on}}.

In 2005 the "S line" trim level, offering new decorative elements, became available and the three-door A3 received the same front-end styling features as the Sportback model. For the first time, the A3 became available in the North American market, exclusively with the Sportback body, with the base 2.0 inline-four FSI introduced in 2005 as a 2006 model, and the 3.2 VR6 Quattro following.

====A3 Sportback (2004–2013)====
The five-door "Sportback" model was introduced in June 2004. The A3 Sportback is {{convert|80|mm|in|1|abbr=on}} longer than the base three-door body, and includes improved rear cabin space and a larger luggage compartment (370&nbsp;litres). It also received the new "single frame" front grille originally introduced in the [[Audi A8|A8 W12]], which was later adopted across the whole A3 range.

====S3 (2006–2013)====
In August 2006, Audi introduced the second generation S3. Offered in three- and five-door body styles, the second generation—''Typ'' 8P—S3 is powered by a modified and uprated Volkswagen Group-sourced 2.0-litre turbocharged FSI petrol engine, with a maximum output of {{convert|195|kW|PS bhp|0|abbr=on}}. As with all Audi S models, the design was done in-house by [[quattro GmbH]]. The engine features uprated high-performance pistons, revised boost/fuel mapping, increased turbocharger size ([[Kühnle, Kopp & Kausch|KKK]] K04) and larger [[intercooler]]. The most powerful form of this engine, and quattro four-wheel drive, makes for a {{convert|0|-|100|km/h|0|abbr=on}} time of 5.7&nbsp;seconds, and an electronically limited top speed of {{convert|250|km/h|0|abbr=on}}. Audi offers both six-speed manual and six-speed S-Tronic automatic transmissions with the S3.

The spring ratings and dampers were revised, along with the body kit. Like its predecessor, although badged a "Quattro" model, the S3 does not employ a [[Torsen]] centre differential (as in other common Quattro models), but instead uses the Swedish Haldex Traction system in its on-demand four-wheel drive transmission, due to the transverse engine layout.<gallery>

Euro NCAP tested a second-generation Audi A3 with front airbags, side airbags, [[seatbelt pretensioner]]s, and load limiters as standard. Despite Audi increasing the protection inside the car for the driver and passengers, pedestrian safety actually got 33% worse compared to the first generation and Euro NCAP gave criticism for the car offering virtually no protection at all on the front end and scoring just one star from a possible four. "A poor result for a new car" was the verdict given for pedestrian safety after the test.{{clear}}

===2016 facelift===
After four years, the third-generation Audi A3 was given a facelift for the model year 2016, which also coincided with the 20th anniversary of the A3 name. The facelifted model was first unveiled through a set of official images in April 2016. The new A3 Saloon was given significant cosmetic updates, which were inline with the automaker's new design philosophy. As a result, the 2017 Audi A3 featured the Matrix LED headlamps that were earlier seen in the [[Audi A8|A8]] flagship saloon and the [[Audi R8|R8]] supercar. The rear taillights also received an optional sequentially animated turn-signal treatment. The front grille was also given a refreshed treatment that made the A3 look like the [[Audi A4#B9|A4]]. Changes on the sides and rear were minimal, with only the taillights getting optional LEDs. There were multiple updates on the interior as well, with a fully digital 12.3-inch instrument cluster screen placed behind a revised steering wheel available as an optional upgrade. Optional features included Apple Carplay and Android Auto, and a suite of driver's assistance features. Sold in Europe and released in the United States for the 2016 model year.<ref>{{Cite web|url=https://www.audiusa.com/models/audi-rs3|title=Audi}}</ref>

The fourth-generation A3 was unveiled on 3 March 2020 as the Sportback model,<ref>{{Cite web |last=Padeanu |first=Adrian |date=2020-03-03 |title=2021 Audi A3 Sportback Debuts With Posh Design, All-New Interior |url=https://www.motor1.com/news/401890/2021-audi-a3-sportback-revealed/ |access-date=2025-05-22 |website=Motor1.com |language=en}}</ref> and the Saloon model was later unveiled on 21 April 2020.<ref>{{Cite web |last=Simone |first=Clint |date=2020-04-21 |title=2021 Audi A3 Sedan Debuts With Fresh Design, New Technology |url=https://www.motor1.com/news/410706/2021-audi-a3-sedan-debut/ |access-date=2025-05-22 |website=Motor1.com |language=en}}</ref>

The new exterior and interior styling is heavily inspired by [[Lamborghini]], LED headlights and taillights, with the option of Matrix LED headlights.{{Citation needed|date=November 2023}} It shares the [[Volkswagen Group MQB platform#MQB evo|MQB evo]] platform with other Audi models, and with the [[Volkswagen Golf Mk8]], [[SEAT León|SEAT Leon Mk4]], and [[Škoda Octavia|Škoda Octavia Mk4]].

It is 3 centimetres longer and wider when compared to the outgoing model while keeping the wheelbase length the same, trunk cargo space is 380 litres with the seats up, and 1200 litres with the seats folded down. It has a drag coefficient of 0.28, and is powered by 1.0-litre 3-cylinder petrol turbocharged engine with 110&nbsp;hp, 1.5-litre  with 150&nbsp;hp, 2.0-litre [[TDI (engine)|TDI]] with 116&nbsp;hp or 150&nbsp;hp.

There is also a new 2.0-litre Quattro version in both petrol and diesel variants. It produces {{convert|190|hp|0|abbr=on}} and {{convert|320|Nm|0|abbr=on}} of torque (400 Nm for the diesel variant). It also has reduced cargo space (320 litres instead of the 380 litres in the other A3 variants) due to the Quattro four-wheel-drive system.

The S3 model has the same 2.0L petrol engine from the previous generation, producing {{convert|310|hp|0|abbr=on}} and {{convert|400|Nm|0|abbr=on}} of torque, but this time is only available with an automatic gearbox. Similarly it has reduced cargo space due to the Quattro four-wheel-drive system. In the United States, the S3 is equipped with the newer EA888.4 2.0L engine shared with the Mk8 Golf R, rated at {{convert|306|hp|0|abbr=on}} and {{convert|400|Nm|0|abbr=on}}.

Like the previous generation, the new S3 also comes as a saloon/sedan.

This generation of the A3 Saloon is not expected to arrive in North America until late 2021, as a 2022 model.<ref>{{cite web|url=https://www.caranddriver.com/news/a33382652/2022-audi-a3-sedan-specs-details/|title=2022 Audi A3 Sedan Has Aggressively Contemporary Look and Feel|first=Jens|last=Meiners|publisher=[[Car & Driver]]|date=2020-07-22}}</ref> North America will not get the ''Sportback e-Tron'' like before. In the countries that will receive The PHEV A3 will no longer be called The e-tron because this name is reserved for electric Audi cars. Instead, it is called The TFSIe. There are 2 version of the TFSIe, called the "40" and the "45". The former dispatches a 0-{{convert|60|mph|0|abbr=on}} time of 7.8 sec, while the latter is based on the Golf GTE and is a second quicker to {{convert|60|mph|0|abbr=on}}.<gallery widths="200" heights="120">

=== Audi RS 3 ===
The highest specification RS 3 model is fitted with a 2.5-litre 5-cylinder producing {{cvt|400|PS|kW hp|0}} and {{cvt|500|Nm|lbft|0}}, and has 0-{{convert|60|mph|0|abbr=on}} acceleration time of 3.8 seconds. It gets a seven-speed dual-clutch automatic S-Tronic gearbox. It also gets the new MMI infotainment system, with a 10.25 or 12.3-inch digital instrument cluster, and a secondary screen of 10.1-inches. With the RS Dynamic package the speed limiter is removed, allowing the RS3 to reach a top speed of {{cvt|290|km/h|mph|0}}.<ref name=RH22>{{cite web | url = https://de.motor1.com/news/616772/audi-rs3-performance-edition-2023/ | archive-url = https://web.archive.org/web/20221021135518/https://de.motor1.com/news/616772/audi-rs3-performance-edition-2023/ | archive-date = 2022-10-21 | first = Roland | last = Hildebrandt | title = Audi RS 3 Performance Edition: 407 PS und Tempo 300 | trans-title = 407 hp and 300 top speed | work = motor1.com | language = de | date = 2022-10-18 }}</ref> The US-market RS3 produces marginally more power than the European RS3, at a claimed {{cvt|401|hp|kW PS|0}}.<ref name=slashRS322>{{cite web | url = https://www.slashgear.com/880403/2022-audi-rs-3-first-drive-special-but-not-how-you-expect/ | archive-url = https://web.archive.org/web/20230827185311/https://www.slashgear.com/880403/2022-audi-rs-3-first-drive-special-but-not-how-you-expect/ | archive-date = 2023-08-27 | title = 2022 Audi RS 3 First Drive: Special, But Not How You Expect | first = Chris | last = Davies | date = 2022-06-01 | work = SlashGear | publisher = Static Media }}</ref> This is partially due to the lack of a [[Gasoline particulate filter|petrol particulate filter]] for US model cars, as it is not required to meet emissions standards. The US-market RS3 instead receives a secondary catalytic converter.

In October 2022, the RS3 Performance Edition was introduced for European buyers. The boost was increased from {{cvt|1.5|to|1.6|bar|psi|1}}, bringing power up to {{cvt|407|PS|kW hp|0}} and thus matching the peak power of the federalized version. Torque remained as before but across a slightly wider range.<ref name=RH22/> The (unlimited) top speed reaches {{cvt|300|km/h|mph|0}}, a first for an A3 based model. Production is limited to 300 units.<ref name=RH22/><gallery widths="200" heights="120">
